PN EU IVIATIC STACKER.

SPECIFICATION forming part of Letters Patent No. 601,356, dated March29, 1898. Application led .Tuly l, 1897. Serial No. 643,173. (No model.)

To all whom it may concern.-

' States, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented a new and useful Pneumatic Stacker, of which thefollowing is a specification.

Our invention relates to improvements in pneumatic straw-stackers.

The objects of our invention are to produce, first, an improvedtelescoping portion for the stacker; second, improved means for chang-.ing the angular position of the stacker-tubes third, an improved hoodconstruction; fourth, improved driving mechanism and means forautomatically controlling the oscillation 4of the stacker-tube; iifth,an improved bearing for the fan-shaft; sixth, improved means forintroducing the straw into the fan-casing, and, seventh, to providevarious improvements in the details of the construction shown in LettersPatent No. 556,776, issued to A. A. Russell March 24, 1396. Y

The accompanying drawings illustrateour invention.

Figure 1 is a view in perspective of the entire stacker. Fig. 2 is acentral vertical section thereof. Fig. 3 is a detail of thehoodoperating means. Fig. 4 is a detail of the fan-shaft bearing. Fig. 5is a detail of the gear-reversing lever. Fig. 6 is a plan of theadjustable hood. Fig. 7 is an end view thereof. Fig. 8 is a perspectiveof the adjustable hood.

In the drawings, 6 indicates the fan-casing, in which is mounted a fan 7of the usual form.

Leading from casing 6 is a discharge-conduit 8. Mounted at the upper endof conduit 8, and revoluble upon a vertical axis thereover, is a pipe 9,to the lower end of which is secured a gear 10, the said gear beingmounted in any suitable bearings. near the lower end thereof, is a band11,'provided with a pair of extending arms 12. Pivoted to the outer endsof arms 12 at 12" are the Vouter ends of a similar pair of arms 13,carried by a band 14, which is secured to a pipe 15. The upper end ofpipe 9 and the cooperating end of pipe 15 are bent into arcs of a circlestruck from the pivotal point 12", and pipe 15 telescopes over pipe 9.Secured to band 11 and extending upward therefrom are Secured to pipe 9,

two standards 16, between which is mounted a reel 17. Secured to theshaft of reel 17 is a worm-gear 18, which coperates'with a worm 19,provided with a hand-wheel 2O or other operating means. For the purposeof swinging pipe -15 around pivot 12 one end of a wire rope 21 issecured to reel 17, the other end being passed over and around a pulley22, carried at the upper side of band 14, and then secured to the upperends of standards 16. It has heretofore been thoughtnecessary to attachthe outer end of the lifting cable or rope at some point near the outerend of the stacker-tube, and in such case a'derrick is erected overwhich the rope is drawn as shown in the patent mentioned above. In thepresent construction the derrick is removed and reel 17 is placed nearthe upper ends of the supporting-standards, so that the direction ofpull from the reel to the pulley 22 is at all times 'substantially inline with the direction of movement, so that the stacker-tube may beeasily lifted;

Mounted so as to telescope over the outer end of pipe 15 is a pipe 23.It is desirable that these two telescoping pipes be so arranged thatwhen brought together theymay occupy a minimum amount of space. Forthispurpose We secure to the upper side of band 14 one end of a bar 24,the arrangement being such that the inner end of pipe 23 may pass"Mounted at theouter andunder the bar. inner ends, respectively,of bar 24are sprocket- Wheels 25 and '26, over whichis passed an endless chain27, which is fastened at one point to theinner end of pipe 23. By thismeans pipe ,23 may pass under bar 24 and the inner end thereof may bebrought back to the sprocket-wheel 26, thus providing for a considerableextension of the telescoping parts, at the same time allowing the partsto be so contracted as to occupy avery short space. Sprocket 26 iscarried bya shaft 28, supported in suitable bearings in band 14. Securedto the outer end of shaft 28 is a hand-wheel 29,

.provided on its inner face with a series of teeth 30, which are adaptedto coperate with a similar series of teeth 31, carried by a reel 32,which is loosely mounted on the shaft. Reel 32 is normally held inengagement with the hand-wheel 29 by means of a spring 33.

For the purpose of deliecting the straw downward as it issues from theouter end of pipe-section 65, hereinafter described,we provide a hood ofthe following construction: A portion of the bottom of the outer end ofpipe 65 is cut away, and to the outer end of the pipe is secured ahollow spherical segment 34. Pivoted at 34" to segment 34, at the endsthereof, is a similar segment 35. Pivoted to segment 35 is a similarsegment 36, and pivoted to segment 36 is a segment 37, any desirednumber of segments being introduced, so as to form an adjustable elbowof the desired angle. segment 37 have secured to it at its outer edge asegment 38, which forms a part thereof. The vari-ous pivoted segmentsare prevented from spreading too far apart by means of a short length ofchain which passes from segment 34 to segment 38 and is secured atintermediate points to the intervening segments.' In order to maintainthe hood in its open position, as shown in Fig. 1, a spring 39 ismounted at each side of the hood, one end of said spring being securedto pipe 65 and the other end secured to segment 37, the arrangementbeing such that the action of the spring is such as to resist thebringing together of the segments. For the purpose of adjusting the hooda cord 40 is secured at one end to the outer segment of the hood and atthe other end is secured to reel 32. Reel 32 is of substantially thesame diameter as sprocket 26 and is held normally `in engagement withthe hand-wheel and shaft which' operate said sprocket. The arrangementis such, therefore, that when the pipe 23 is moved in either directionupon pipe 15 the cord 40 is l Wound upon or unwound from reel 32 atsubstantially the same rate, so that the length of the stacker-tubemaybe adjusted without in any manner interfering with the adjustment ofthe hood.

When it is desired to adjust the hood, the operator separates reel 32and hand-wheel 29 and then turns the said reel in the desired di-Arection. For the purpose of oscillating the stacker we provide thefollowing mechanism: l Gear 10 is supported in suitable bearings carlried by a framework which forms a part ofl or may be attached to aseparator of any desired type. Supported in suitable bearings mesh withgear 10.

the clutch-teeth of the gears. tween gears 44 and'45 and intermeshingtherewith is a bevel-gear 47, which is secured to one end of a shaft 48.Mounted upon shaft 48 and revoluble thereon is a gear 49, which It ispreferable that the last may be engaged by a clutch 50, keyed to theshaft. Clutch 50 may be thrown out ofl engagement with gear 49 by meansof a bellcrank lever 5l and rod 52. Gear 49 may be driven by anysuitable means, such as worm 53 and pulley 54. Pivoted to the frameworkis a lever 55, arm 56 of which is adapted to engage clutch 46 and shiftthe same along shaft 41. Arm 57 of lever 55 projects over gear 10 inposition to be engaged upon either side by one or the other of a pair ofpins 58, which may be placed in any one of a series of holes 58, formedin gear l0, the arrangement being such that as the gear lO is rotated ineither direction by the train of gears just described one of pins 5Swill come into engagement with arm 57 of lever 55 and will swing thesaid lever upon its pivot and shift clutch 46,thus reversing thedirection of movement of Worm 42 and gear l0. As gear lO is moved in thereverse direction the other pin 58 is brought into engagement with arm57 and the direction of movement of the gear is again reversed. Theangle of swing of gear l0 and the stacker-tubes carried thereby may beregulated by changing the positions of pins 58. In order tomaintainclutch 46 in engagement with either one of gears 44 and 45 and in orderto throw the said clutch quickly out of engagement with one gear andinto engagement with the other, arm 56 of lever 55 is provided with aforked end 59, which straddles the clutch and lies between a pair ofcollars which are sufficiently separated to allow the forked end 59considerable longitudinal play. Mounted upon arm 57 of lever 55 andlongitudinally movable in suitable bearings there* on is a catch 60,provided with a V-shape'd head 6l, adapted to engage a stationary pin62. Catch 60 is yieldingly held in its normal position by means of aspring 63.

In operation when one of pins 58 comes into engagement with arm 57 oflever 55 the lever is swung upon its pivot, the forked end 59 of arm 56thereof swinging freely between the collars of clutch 46. This movementof the lever forces the V-shaped head of catch 60 against pin 62 andthus forces the catch backward against the action of spring 63. As soonas head 61 passes the center of pin 62 spring 63 forces the said headforward, thus quickly bringing fork 59 into engagementl with one of thecollars of clutch 46 and shifting the said clutch along the shaft out ofengagement with one and into engagement with the other of gears 44 and45.

It has heretofore been customary to place in the blast-fan casing aspreading cone, which operates to spread the straw after it has enteredthe casing. The great difiiculty has been to make the fan, thefan-casing, and the eye of the casing of such proportions that the strawwould be properly removed from the casing with as small an expenditureof power as possible. made sufficiently large to easily admitall of thestraw, then in order to create sufficient IOO If the eye of the casingis Y side of section 65. The opposite ends of cords draft the fan mustbe so large as to consume a large amount of power. In the presentconstruction we place the spreading-cone 64 in the eye of the casing,but outside of the casing, the bottom of the cone being substantiallyinline with the top of the casing. By this meansthe eye of the casing isdiminished in size; but the straw is separated and spread just at thepoint of entrance into the casing,

so that it easily enters into the eye and may be quickly disposed of bythe fan. The cone may be supported upon the upper end of the fan-shaft,as shown in the drawings, or in any other desirable manner.

In'order to support the fan-shaft, we mount the lower end of said shaftwithin a socket or bearing 66, in the bottom of which is placed a diskor hardened bearing-plate 67. Between plate 67 and the end of the shaftis placed a series of balls 68. In order to adjust the bearing and toregulate the position of the fan within the casing, a set-screw 69 isplaced to engage the lowerface of plate 67 and to support said plate atany desired point within the socket.

It is often desirable to be able to throw the threshed straw into a barnor mow. With the ordinary construction, in which the hood is mounteddirectly upon the outer end of the pipe 23, such disposition of thestraw is practically impossible. W'e therefore mount upon the outer endof pipe 23 a short section of pipe 65, which may be rotated upon pipe23, the section 65 being held in longitudinal position by means of bolts70, which are secured to pipe`23 and passed through circumferentialslots7l, formed through'section 65 near the inner end thereof. Secured to theouter end of section 65, in the'manner already described, is theadjustable hood, consisting of the Various segments 34 to 3S, inelusive.

Mounted near the outer end of pipe 23 are two pulleys 72 and 73, overwhich are passed cords 74 74, the outer ends of said cords being securedto a bolt 7 5, mounted on the under l. In a pneumatic stacker, thecombination I with a pair of telescoping tubes, of a band secured toeach tube, an arm carried by each band, the two arms being pivotedtogether, a standard carried by one of the bands, areel carried'bythestandard, means for operating the reel, a pulley carried by the otherband,

land a cord secured at one end to the reel,

passed around the pulley, and secured at the other en'dto the standard,substantially as and for the purpose set forth.

2. In a pneumatic stacker, a hood for the outer end of the tube thereof,the said hood consisting of a series of hollow spherical segments eachof said segments beingppivoted at each end to the adjacent `ends of thepreceding segment only, and a spring, the ends of which are secured tothe outer segments the arrangement being such that said spring will tendto spread or separate the segments.

3. In a pneumatic stacker, the combination with the fan-casing thereof,of `a spreadingcone mounted in the eye thereof, the said cone projectingabove the easing.

4t.' In a pneumatic stacker, the combination l with the fan-casingthereof, of a spreadingcone l,mounted in the eye thereof, said coneprojecting from the casing andthe bottom thereof being substantially inline with the top of the casing.
